Definitely agree on the used ThinkPad. You can get some surprising deals from businesses offloading even relatively recent machines that are still in very good condition (used to daily drive a T14 Gen 3 that was half the price of when it was new despite being only two years old and still in warranty). However, new ones do still retain very good compatibility (no issues on my P14s Gen 5), although the price point does make a Framework the obvious other option to look at, especially due to the better upgrade and repair situation (soldered WiFi modules on newer ThinkPads are really annoying).

I use Pika Backup (GUI that uses Borg Backup on the backend) to back up my desktop to my home server daily, then overnight that server has a daily backup using Borg to a Hetzner Storage Box. It’s easy to set it and forget it (other than maybe verifying the backups every once in a while), and having that off site back up gives me peace of mind.

Definitely agree. The KDE spin used to have some quirks and bugs, but have been running it on my laptop as a daily driver for nearly six months with no real issues and it is rock solid reliable. Fedora also has a ton of community and commercial support so pretty much any Linux app will work fine on there.
